The desired goal was that everywhere I construct a value using the Assign

Your code essentially accomplishes the goal:
data E m where
Assign :: AssignCap m = V - E m - E m - E m
Hi all,
Is there something wrong with the code below? My anticipation was that the
type of test would include the class constraint, because it uses the
Assign constructor. But if you load this code in GHCI you can see that the
inferred type was test :: E m - E m.
Thanks,
